About this Digital Standard
3 About this Digital Standard
GSM is a TDMA standard for cellular mobile radio networks and is used worldwide.
Every TDMA frame consists of 8 timeslots (or simply "slots"). Each slot can be separately turned on or off. A maximum of 7 different level attenuation values can be
defined and allocated separately to the 8 slots quite independently of one another.
In order to configure a slot it is necessary to define a burst type. Different burst types
are available, depending on the installed options. Available are burst types defined for
normal symbol rate and higher order modulation schemes as well as with the burst
types defined for higher symbol rates HSR.
Higher symbol rates are achieved by reduction of the symbol period and employing of
higher symbol rate bursts (HB) instead of the normal burst (NB). A normal burst contains 116 encrypted symbols and uses time slots with normal duration (156 or 157
symbols long). The higher symbol rate bursts carry information on full rate packet traffic channels, contain 138 encrypted symbols and use time slots with reduced symbol
duration (187 or 188 symbols long).
The modulation data is continuously inserted into the chosen slots (in realtime). In this
fashion the data generator uses a digital signal processor to generate a data stream
complete with modulation data and control signals for power ramping.
This data stream is converted into I/Q signals in the modulation encoder.
The R&S SMW processes the signal depending on the configured modulation scheme
and selected symbol rate mode:
●
In accordance with the GSM standard, the MSK modulation type is set by default to
a symbol rate of 270.833 ksymb/s and Gauss filtering.
You can adjust the symbol rate. Additionally, you can use a FSK modulation with
configurable span.
●
In accordance with the standard, in the case of EDGE slots the 8PSK modulation
type is set by default to 3/8 rotation at a symbol rate of 270.833 ksymb/s and
Gauss linearized filtering.
●
In accordance to EDGE Evolution specifications (option R&S SMW-K41), the
EDGE Evolution slots in a normal burst (NB) are 16QAM or 32QAM modulated at a
symbol rate of 270.833 ksymb/s and Gauss linearized filtering. The EDGE Evolution slots in a higher symbol rate bursts (HB) are QPSK, 16QAM or 32QAM modulated at a symbol rate of 325 ksymb/s and spectrally Narrow or Wide Pulse Shape
filtering.
●
In accordance to VAMOS specifications (option R&S SMW-K41), the slots are
AQPSK modulated at a symbol rate of 270.833 ksymb/s and Gauss linearized filtering.
You can configure the GSM/EDGE signal in on of the following modes:
●
Mode Unframed - a signal with standard-compliant modulation parameters but
without slot and frame structure is generated.
●
Mode Frame (Single) - a signal consisting of a frame is generated; it is also possible to choose half rate bursts and to define multi slots.

About this Digital Standard
VAMOS (Voice services over Adaptive Multi-user channels on One Slot)
●
Mode Frame (Double) - a signal consisting of two frames is generated; the frames
are repeated according to a defined default.
3.1 VAMOS (Voice services over Adaptive Multi-user
channels on One Slot)
According to 3GPP TS 45.001, with VAMOS it is possible to serve two MS simultaneously on the same physical resource. Thus the voice channel capacity in the CS
domain can be doubled.
Each of the two VAMOS users is assigned a so-called VAMOS subchannel, i.e. the
physical radio resource is split into two subchannels, one for each VAMOS user. The
two subchannels are separated in uplink and downlink via training sequences. For this
purpose 3GPP TS 45.002 defines two sets of Training Sequence Codes (TSC). One
VAMOS user/subchannel gets a training sequence from TSC set 1, the other from TSC
set 2. This ensures that the two training sequences have a very low cross-correlation.
All mobiles must support TSC set 1, but only mobiles explicitly indicating support for
VAMOS must also support TSC set 2.
In the uplink two GMSK modulated signals interfere with each other and the base station receiver requires an advanced multi-user detection algorithm.
In the downlink a novel modulation scheme is used for each subchannel. The two subchannels are combined orthogonally by mapping them to the I and Q axis. This results
in a QPSK modulation scheme, where each constellation point has a subchannel 1
component and a subchannel 2 component, as shown in the following figure.
Fig. 3-1: QPSK modulation, sum of both subchannels
In this figure both subchannels use the same power level. VAMOS allows subchannelspecific power control, so that the two subchannels can use different power levels, e.g.

R&S®SMW-K40/-K41
About this Digital Standard
VAMOS (Voice services over Adaptive Multi-user channels on One Slot)
when the two users are located at different distances from the base station. The resulting modulation scheme is called Adaptive QPSK (AQPSK). The following figure shows
an example where subchannel 2 mapped to the Q-axis uses a higher power level than
subchannel 1 mapped to the I-axis.
Fig. 3-2: AQPSK modulation, subchannel 2 with higher power level
The power level of subchannel 2 relative to the power level of subchannel 1 is called
Subchannel Power Imbalance Ratio (SCPIR). It is related to the angle α as follows:
SCPIR = 20 * log10(tan α) dB,
where the value of α shall be chosen such that |SCPIR|≤10dB
For α = 45° the SCPIR equals 0 dB and the two power levels are equal.
AQPSK modulation is applied in the downlink if speech frames have to be transmitted
on both subchannels simultaneously.
In this implementation, you can set the SCPIR and configure the VAMOS subchannels,
TSC set and TSC used. The available VAMOS settings depend on the mode the signal
is generated in:
●
"Unframed"
Two data sources are provided, one per each VAMOS subchannel; the data is
AQPSK modulated but only one SCPIR can be configured.
●
"Framed (Single)"
Full Rate, Half Rate and combination of both slot types are supported. The characteristics of each of the half rate slots can be adjusted individually
Separate data source is provided per each VAMOS subchannel and each user in
half rate mode; the data is AQPSK modulated and eight SCPIRs can be configured
Training Sequence (TSC) set and TSC used can be configured on a VAMOS subchannel/User basis
●
"Framed (Double)"
The settings of each of the two frames are as in the "Framed (Single)" mode.

Trigger Settings
This dialog comprises the settings required for configuring the trigger signal.
Routing and Enabling a Trigger
The provided trigger signals are not dedicated to a particular connector but can be
mapped to one or more globally shared USER or local T/M/(C) connectors.
Use the Local and Global Connector Settings to configure the signal mapping as well
as the polarity, the trigger threshold and the input impedance of the input connectors.
To route and enable a trigger signal, perform the following general steps:
●
Define the signal source and the effect of a trigger event, i.e. select the "Trigger In
> Mode" and "Trigger In > Source"
●
Define the connector, USER or T/M/(C), the selected signal is provided at, i.e. configure the Local and Global Connector Settings.
Trigger Settings Common to All Basebands
To enable simultaneous signal generation in all basebands, the R&S SMW couples the
trigger settings in the available basebands in any instrument's configuration involving
signal routing with signal addition (e.g. MIMO configuration, routing and summing of
basebands and/or streams).
The icon
indicates that common trigger settings are applied.
You can access and configure the common trigger source and trigger mode settings in
any of the basebands. An arm or a restart trigger event applies to all basebands, too.
You can still apply different delay to each of the triggers individually.

"On"
Corresponds to the default state of this parameter.
The signal calculation starts simultaneously with the external trigger
event but because of the instrument’s processing time the first samples are cut off and no signal is output. After elapsing of the internal
processing time, the output signal is synchronous to the trigger event.
"Off"
The signal output begins after elapsing of the processing time and
starts with sample 0, i.e. the complete signal is output.
This mode is recommended for triggering of short signal sequences
with signal duration comparable with the processing time of the

In "Unframed" mode a modulation signal without slot or frame structure is generated.
The modulated carrier without power ramping is often enough for initial tests, and in
case the complete signal is not yet needed.
Since all the modulation parameters for the signal are conform to the standard, only
the symbol rate mode (normal or higher symbol rate) and the modulation (MSK or FSK
for GSM, 8PSK EDGE for EDGE and 16QAM EDGE or 32QAM EDGE for EDGE Evolution) have to be selected. The symbol rate and filter configuration are set accordingly.
This mode can be used for quick measurements of the spectrum or signal quality (e.g.
EVM).

Mode Framed (single)
This dialog displays the frame structure and provides access to the dialog for saving and loading a frame structure.
The "Framed (single)" mode generates a modulation signal which is defined by the
structure of a single frame. The frame structure is repeated cyclically, but the useful
data is continuously generated.
The frame structure is displayed in graphical form. Slot parameters can be defined in
the burst editor, which is called when the slot is selected in the graphical display (see
chapter 4.12, "Burst Editor", on page 46). You can define half rate slots. The characteristics of each half rate slot can be defined separately. Each active slot is represented by a burst symbol. Two half rate slots occupy the space of a full rate slot. A slot in
which the level has been attenuated is represented by a lower amplitude burst. Inactive
slots (Slot Level = Off) are shown as a horizontal bar. If multislots have been defined,
the banded slots are surrounded by a frame (slots 5 to 7 in the illustration).
When a half rate slot has been selected, two frames are generated alternately. Each
frame holds one of the two half rate users.

Mode Framed (double)
This dialog displays the frame structure and gives access to the dialog for saving

The "Framed (double)" mode generates multiframe signals which are defined by the
structure of two frames.
For this purpose two frames are defined as in "Framed (single)" mode. A repetition factor is then specified for each of the two frames. Following a trigger the first frame is
repeated the specified number of times, and then the second frame. The frame structures are repeated cyclically, but the useful data is continuously generated.
If one of the frames contains half rate slots (and so actually consists of 2 frames itself),
the repetition factor must be a multiple of 2 (seechapter 4.7, "Mode Framed (single)",
on page 27 ).
The frame structure of the two frames is displayed in graphical form. Slot parameters
can be defined in the burst editor, which is called when the slot is selected in the

Ignore 1/4 symbol (slot length 156 sym) / Ignore ½ symbol (slot length 187 sym)
Selects constant slot length. This setting affects all burst types.
In a normal burst (NB), the GSM slot has a length of 156.25 symbols. Compensation
for the 1/4 symbol takes the form of an extra symbol every 4th slot. This means that
some slots are 156 long and some are 157 long. Compensation takes place in the
guard field of the burst (seechapter 4.12, "Burst Editor", on page 46 ).
In a higher symbol rate burst (HB), the average slot is 187.5 symbols long. Compensation for ½ symbol means that each second slot gets an extra symbol and is 188 symbols long, while the rest uses a slot length of 187 symbols.
If the field "Ignore 1/4 symbol (slot length 156 symbols) / Ignore ½ symbol (slot length
187 symbols)" is enabled, all slots are 156 respectively 187 symbols long. The extra
1/4 resp. ½ symbol is omitted. The guard field for the burst always has the same length
regardless of the slot index.
For normal burst, a frame is therefore 1248 symbols long instead of 1250.
Respectively, the length of the frame in a higher symbol rate burst is then 1496 symbols long instead of 1500 symbols.

individual slots.
Remote command:

Baseband Only
Restricts power ramping to the baseband signal.
"Off"
Level attenuation is effected via the attenuator stages in the RF section; only the remaining part is attenuated in the baseband. The signal is issued at the RF output with the defined level values. This setting provides the best possible dynamic for bursted signals.
"On"
Level attenuation affects the baseband only.
This setting is mandatory in the following cases:
●
When only the baseband signal is issued at the I/Q outputs. It is
thus ensured that, with power ramping active, this signal is output
with the defined level values.
●
When a baseband signal is applied to two RF paths of an twopath instrument. The RF paths having separate frequency and
level settings, the remaining attenuation to be effected in the
baseband would have to be different for the two paths and is
therefore not possible.
●
When a bursted baseband signal (GSM/EDGE) is combined with
a continuous baseband signal (e.g. 3GPP) or a noise signal and
both signals are applied to one RF path of an two-path instrument. Blanking in the RF paths is not suitable, because the RF
section would not only blank the bursted signal of the first baseband but also the continuous signal of the second baseband or
the noise signal.

VAMOS mode, both interference and sensitivity limited cases are specified for VAMOS
subchannel 1 that is offset in time and frequency with respect to VAMOS subchannel
2. If this parameter is activated, the instrument applys a timing offset (jitter) with randomly selected value in the range of -1, 0 or 1 symbol period. The timing offset
changes between the bursts; within a burst, the instrument keeps the time and frequency offsets constant.
Use the frequency offset parameters μ and σ to define the required gaussian frequency
jitter.

5 Remote-Control Commands
The following commands are required to perform signal generation with the GSM/
EDGE options in a remote environment. We assume that the R&S SMW has already
been set up for remote operation in a network as described in the R&S SMW documentation. A knowledge about the remote control operation and the SCPI command
syntax are assumed.
Conventions used in SCPI command descriptions
For a description of the conventions used in the remote command descriptions, see
section "Remote Control Commands" in the R&S SMW user manual.
Common Suffixes
The following common suffixes are used in remote commands:
Suffix

in Frame (Double) mode (SOURce:BB:GSM:MODE
DOUBle) this suffix defines the frame to which the
setting applies
in Frame (Single) mode the keyword FRAMe is
ignored and can be omitted
defines the slot to which the setting applies
Note: SCPI prescribes that suffix 1 is the default state and
used when no specific suffix is specified. Therefore, slot 1
(and not slot 0) is selected when no suffix is specified.
SUBChannel<us>
[1]|2
defines the VAMOS subchannel
USER<ch>
[1]|2
defines the half rate user in a half rate mode
Using SCPI command aliases for advanced mode with multiple entities
You can address multiple entities configurations by using the SCPI commands starting
with the keyword SOURce or the alias commands starting with the keyword ENTity.
Note that the meaning of the keyword SOURce<hw> changes in the second case.
For details, see section "SCPI Command Aliases for Advanced Mode with Multiple
Entities" in the R&S SMW user manual.

Sets the sequence length of the generated arbitrary waveform file in number of frames.
This parameter applies to GSM modes Single or Double framded.
For GSM mode Framed Double, this command is query only, since the length of the
generated ARB file is determined by the parameter Frame Repetition ([:
SOURce<hw>]:BB:GSM:FRAMe<di>:REPetitions) for both frames:
Sequence Length = Frame Repetition of Frame 1 + Frame Repetition of Frame 2.
For GSM mode (BB:GSM:MODE) set to Unframed, the length of the generated ARB file
is set in symbols with the command [:SOURce<hw>]:BB:GSM:SLENgth.

Remote-Control Commands
Trigger Settings
Parameters:
<Sequence>
AUTO | RETRigger | AAUTo | ARETrigger | SINGle
AUTO
The frames are generated continuously.
RETRigger
The frames are generated continuously. A trigger event (internal
or external) causes a restart.
AAUTo
The frames are generated only when a trigger event occurs.
After the trigger event the signal is generated continuously. Signal generation is stopped with command
SOUR:BB:GSM:TRIG:ARM:EXEC and started again when a trigger event occurs.
ARETrigger
The frames are generated only when a trigger event occurs. The
device automatically toggles to RETRIG mode. Every subsequent trigger event causes a restart. Signal generation is stopped with command SOUR:BB:GSM:TRIG:ARM:EXEC and started again when a trigger event occurs.
SINGle
The signal is generated only when a trigger event occurs. After
the trigger event the signal is generated once to the set
sequence length (SOUR:BB:GSM:TRIG:SLEN). Every subsequent trigger event causes a restart.
*RST:
AUTO
Example:
BB:GSM:SEQ AAUT
sets the "Armed_auto" trigger mode; the device waits for the first
trigger (e.g. with *TRG) and then generates the frames continuously.
Manual operation:
See "Trigger Mode" on page 17
[:SOURce<hw>]:BB:GSM:TRIGger:ARM:EXECute
The command stops signal generation for trigger modes Armed_Auto and Armed_Retrigger. A subsequent internal or external trigger event restarts signal generation.
Example:
User Manual 1175.6684.02 ─ 07
BB:GSM:TRIG:SOUR INT
sets internal triggering.
BB:GSM:TRIG:SEQ ARET
sets Armed_Retrigger mode, i.e. every trigger event causes signal generation to restart.
BB:GSM:TRIG:EXEC
executes a trigger, signal generation is started.
BB:GSM:TRIG:ARM:EXEC
signal generation is stopped.
BB:GSM:TRIG:EXEC
executes a trigger, signal generation is started again.

[:SOURce<hw>]:BB:GSM:TRIGger:EXTernal:SYNChronize:OUTPut <Output>
(enabled for "Trigger Source" External)
Enables/disables output of the signal synchronous to the external trigger event.
Parameters:
<Output>
0 | 1 | OFF | ON
ON
The signal calculation starts simultaneously with the external
trigger event but because of the instrument's processing time
the first samples are cut off and no signal is outputted. After
elapsing of the internal processing time, the output signal is synchronous to the trigger event.
OFF
The signal output begins after elapsing of the processing time
and starts with sample 0, i.e. the complete signal is outputted.
This mode is recommended for triggering of short signal sequences with signal duration comparable with the processing time of
the instrument.
*RST:
ON
Example:
BB:GSM:TRIG:SOUR EXT

Note: This command is available for instruments with RF output only.
Selects power ramping in the baseband only or mixed power ramping in the baseband
and the RF section. The "ON" setting is mandatory if, with power ramping active, only
the baseband signal is output (I/Q outputs), or, in case of two-path instruments, if a
baseband signal is applied to two RF paths (RF A and RF B).
Only then can a signal with a defined, predictable level be output.
Parameters:
